StatusActive Development

Executive Summary

Finishi is a comprehensive AI-powered learning platform that transforms scattered self-learning into structured, goal-oriented educational journeys. The platform combines personalized learning paths, AI tutoring, progress tracking, and accountability features to help learners complete what they start.

The project encompasses five interconnected services: a learner-facing application, an administrative dashboard, a shared API backend, a marketing waitlist site, and supporting infrastructure—all built with modern, scalable technologies.

The Challenge

Self-directed learners face a common problem: abundant resources but no structure. Courses, tutorials, and content pile up, leading to:

Content overwhelm

Too many options with no clear direction

Lack of accountability

No streaks, reminders, or progress tracking

Incomplete learning

Starting many courses but finishing few

Finishi needed to solve these problems while delivering a polished experience across multiple user roles (learners and administrators) with AI-powered personalization at its core.

Solution Architecture

Multi-Service Platform Design

We architected Finishi as a distributed system with clear separation of concerns:

Technical Highlights

API Architecture

The API follows a modular, domain-driven design:

src/
├── admin/          # Admin-specific routes and logic
├── ai/             # AI provider abstraction and routes
├── auth/           # Authentication (email, Google OAuth)
├── billing/        # Subscription management
├── events/         # Community and tech events
├── focus/          # Focus session tracking
├── learning/       # Courses, lessons, paths, quizzes, skills
├── monitoring/     # Request logging and system metrics
├── notifications/  # Push and in-app notifications
├── onboarding/     # User onboarding flow
├── shared/         # Plugins, middleware, utilities
└── user/           # User profile and preferences

Each domain module is self-contained with:

Route definitions with Zod schema validation
Type definitions for request/response contracts
Business logic isolated from HTTP handling

Authentication & AuthorizationJWT-based Auth with access and refresh tokens
Google OAuth integration for social login
Role-Based Access Control — User vs Admin permissions
Plan-Based Gating — Feature access tied to subscription tier

AI Provider Abstraction// Fallback chain configuration
AI_FALLBACK_CHAIN: 'gemini,groq,openrouter'

// Each provider implements a common interface:
interface AIProvider {
  name: string
  complete(options: CompletionOptions): Promise<CompletionResult>
  assistantChat(options: AssistantOptions): Promise<AssistantResult>
}

Deployment Pipeline

Automated CI/CD with GitHub Actions:

Code push triggers build
